Answer:
82.5 ft²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = 
h (b₁ + b₂)
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 7.5, b₁ = 7 and b₂ = 15 , then
A = × 7.5 × (7 + 15) = 0.5 × 7.5 × 22 = 82.5 ft²

Answer:
B. 12 days
Step-by-step explanation:
This can be set up as an equation:
64x = 768, where x represents the days it will take to achieve 768 doughnuts.
Divide both sides by 64.
x = 12.
It will take 12 days to make an additional 768 doughnuts.
